INSTALLATION

PROCEDURE

1. INSTALL PIPING CLAMP (for Suction Hose Sub-assembly Side)

(a) Remove the vinyl tape from the suction pipe sub-assembly and suction hose sub-assembly.

(b) Install a new piping clamp to the suction hose sub-assembly. NOTICE: Securely engage the piping clamp to the groove of the suction hose sub-assembly. Do not open the piping clamp more than the diameter of the suction hose sub-assembly when installing it. Do not install the piping clamp with the large diameter section facing the wrong direction.
